OK next step on my car is to replace the calipers, i was told this would be a pretty easy job which is good news b/c a shop wanted to charge me 600 bucks for calipers/pads.
What steps should i take in order to do this correctly, this dude i work with said i could disconnect and pinch the brake line while i swap the calipers although i figure if i am gonna do this i should go the whole nine and drain the brake fluid.
To do the brake fluid do i just need to disconnect the line and pump the brake pedal until its dry?
Was also told once i get the caliper on to loosen the bleed screw and have someone pump the pedal until it bleeds out then shut the valve off,
does that sound pretty close?
Thanks for any responses, your savin me buku bucks :)

There is no need is draining the brake fluid unless you put oil in your master cylinder instead of your valve cover or something like that.
Now, to replace the calipers. DO NOT pinch closed the rubber brake line going to the caliper. The rubber hose is lined with sort of a plastic tube if you will to prevent the brake fluid from deteriorating the rubber hose and to prevent the hose from collapsing. Simply have your new caliper in your lap or within reach and screw the brake line into it as quick as you can to prevent loosing too much fluid. I sometimes if my hands are clean will cap off the end of the line with my thumb after I remove the factory caliper. It is always best to have a catch pan under the line though. It's really not that hard. After you do it once you will be able to do it from here on out. I think brake work is about my favorite thing to do on public vehicles.
Bleeding your Brakes, You want to begin by making sure your master cylinder has the suggested amount of fluid in it before you start bleeding any fluid out. Then begin bleeding your brakes at the point farthest from the master cylinder. That should be the passenger rear wheel. To bleed your brakes you will need to get someone to pump the brake pedal a few times and then hold it on the floor. While they are holding strong you need to crack open the bleeder screw then close it back up. After you have closed the bleeder screw the person helping you needs to pump the brakes again before you can bleed any more air/fluid out. Repeat this process until you are getting solid fluid coming out of the bleeder screw. Now you are finished bleeding the passenger side rear wheel. You will need to go from there to the driver side rear wheel, then to the passenger side front wheel, then to the driver's side front wheel. Thats the suggested order to follow when properly bleeding your brakes.
Note: Keep an eye of the master cylinder while you are bleeding your brakes. You may have to add fluid to keep it at the fill line.
Good luck. Let me know if you need any more help.
